BACKGROUND

1. Field of Invention and Prior Art

This section is not Applicable to Provisional Applications. However, as far as known, there are no dynamic, multi-impact golf club assist device this instant device. It is believed that this product is unique in its design and technologies.

2. Background of the Invention

The game of golf has enjoyed increasing popularity in the United States and other countries over the years. Golf requires that players strike a golf ball in as few shots as possible from a tee box into a hole located on a golf green some distance from the tee box. The initial shot from the tee box, commonly known as the drive shot, often determines the success or failure of a player on any particular hole since the closer the drive shot lies to the green, the easier for the player to chip the ball onto the green and/or putt the ball into the hole in as few strokes as possible. The tee shot in golf is made typically using a golf driver. A conventional golf driver includes an elongated, flexible shaft with a solid wooden or metal driver head on the end. The driver head has curved rear and side surfaces along with a flat front surface or face plate which contacts the ball during a drive shot. The face plate is elongated and includes a heel area adjacent to the shaft, a toe area toward the end portion of the driver head, and a center area between the heel area and the toe area.

During a drive shot, it is desirable to contact the ball with the center area of the front face/ impact plate, since such contact often results in a straight and long-distance ball trajectory. If during a drive shot the heel area of the front face/ impact plate contacts the ball, then the ball will often “hook”, or travel in a curved trajectory to the left (in the case of a right-handed player). On the other hand, if the toe area of the face plate contacts the ball, then the ball will often slice or travel in a curved trajectory to the right. Therefore, consistent striking of a golf ball in an optimum manner with a conventional golf driver requires a high degree of skill which typically can only be mastered through routine long-term golf play or practice.

Problem Solved

Therefore, a golf driver is needed which is capable of consistently generating a long-distance and generally straight ball trajectory upon striking of a golf ball whether the ball contact point is at the heel area, the toe area or the central area of the driver. This improvement to the driver head with the encased pistons means a golfer does not need to hit the ball precisely in the same spot every time. The pistons help to compensate and give a secondary impact to correct the ball in relation to the driver heel or toe contact point.

One of the many problems encountered by golfers is the tendency to engage the front face/ impact plate of the club head with the ball in a manner that causes the ball to deviate from the desired path of flight. Generally, a golfer will have a tendency to slide the ball, hook the ball or drive the ball straight and will consistently drive the ball in the same manner. That is, if a person slices the ball, he usually will consistently slide the ball on each drive off the tee or if he has a tendency to hook the ball, he usually will hook the ball when he drives off each tee. While this tendency can be compensated for to a degree by varying the position of a golfer in relation to the golf ball and desired flight path, this does not effectively serve the problem inasmuch as substantial distance is lost when the ball is either sliced or hooked. Accordingly, it is an object of the present invention to construct a golf club head with movable weights therein which will counteract the tendency to slice or hook the golf ball and increase the distance where the golf ball is driven as well as increase the degree of accuracy of the flight path.

An additional object is to provide an momentum generating golf club in which a plurality of small dense weights which are carried within a forwardly placed cylindrical chamber within the club head. This chamber may also relate to a chamber that is non-cylindrical but shaped to provide a forwardly placed void to accomplish the same intent as the cylindrically shaped chamber depending on manufacturers' processes. One of the objects of the present invention, therefore, is to provide for constructing the head of a driver type golf club with a movable weight therein which acts to increase the distance that a golfer is able to drive a ball.

Prior Art

Other weight distributing systems for golf clubs have been provided in prior art. For example, U.S. Pat. 4,039,012 issued to Cook in 1977 shows a hammer having a hollow cylindrical head filled with recoil inhibiting pellets such as lead shot, and having its ends closed by metallic end caps each having an exterior impact surface. A handle-forming skeletal rod is centrally connected to the head, and said head and rod are encased within a unitary resilient encasement leaving the two impact surfaces exposed. Next, U.S. Pat. 4,461,481 issued to Kim in 1984 shows a driver type of golf club is provided which includes a hollow metal head having integrally formed thereon a front striking face/ impact plate and a rear wall with interior flat portions, and a removable sole plate. A rod having a back plate integrally formed on the rear thereof has a cylindrical weight slidably mounted thereon. The rod is fixed in position within said hollow metal head with its back plate anchored against the interior flat portions on the rear wall thereof and with its front end held in an opening provided in a front plate anchored against the back of the striking face. At the instant of impact of the striking face of the head with a golf ball, the cylindrical weight is propelled to freely slide along the fixed rod to hit the front plate on the back of the striking face, and therefore the ball, with a delayed impulse which creates an additional transfer of momentum to the ball thereby increasing the distance that the ball travels. A U.S. Pat. No. 5,195,747, was issued in 1993 to Choy that demonstrates a golf club which has an elongated shaft, a grip, and a club head. The club head has an annular channel having a free moving weight therein which maintains the center of inertia of the club head in the same location regardless of the swing plane of the golf club.

Another U.S. Pat. No. 5,366,222 was issued to Lee in 1994 that shows a wood golf club head includes a golf club head cavity, a steel ball within the golf club head cavity, and a permanent magnet plate attached to the back side of the club head cavity whereby upon hitting the golf ball, the steel ball moves and hits an inner sweet point corresponding to a sweet point of the front surface face of golf club head, so that the struck ball will fly in a straight direction and in a longer distance compared with an expected golf ball distance. A further U.S. Pat. No. 6,149,533 issued in 2000 to Finn provides a golf club includes a head having a striking face, a threaded cylindrical chamber behind and generally parallel to the face, a cylindrical weight member threaded in the chamber, a hosel attached to the cylindrical weight member having a shaft receiving socket with a non-circular portion and a threaded portion, a shaft having a hosel engaging end with a mating non-circular cross section and a ferrule having threads engagable with the threaded portion of the socket. An additional weight is adjustable in the chamber to provide the desired balance characteristics to the club. A second embodiment includes a head which is symmetrical so that the hosel may be attached at either end to make the club ambidextrous. Some different structures for attaching the hosel to the cylindrical weight member provide for variations in the loft of the club. Other embodiments include an asymmetrically weighted movable weight member which engages the head within a cavity therein and is adjustable both longitudinally and by changing the location of its center of gravity. A tool mates with each of the adjustments to provide complete and accurate club assembly and adjustment. Still another U.S. Pat. No. 4,944,515 was issued in 1990 to Shearer that teaches a cast metal hollow headed golf club head having there within at least one internal structural support member disposed between the rear of the club head and the face of the club head, a first end of the internal structural support member being positioned at the geometric center of the face of the club head and a second end of the structural support member opening through the rear surface of the hollow headed golf club and having an open bottom thereto which a bottom plate is permanently secured after the internal cavity of the hollow headed golf club is filled with a sound-proofing material, the internal structural member adapted to house additional metal or similar material to predetermine the resulting weight of the golf club head.

In 1971 a U.S. Pat. No. 3,589,731 was awarded to Chancellor, Jr. that describes a golf club head incorporating a hollow interior with a movable weight supported on a mounting rod which can be oriented in different angular positions to counteract the tendency of a golfer to hook or slice the ball and to increase the distance which the ball is driven due to the additional forces exerted on the ball by the movable weight. The movable weight is centered on the mounting rod by spring devices and the overall shape and configuration of the golf club head is not changed. Another prior art device is demonstrated by U.S. Pat. No. 5,613,916 issued to Sommer in 1997. This patent shows Sports equipment for ball games comprising a stroke portion and a shaft portion including a grip, in particular a tennis racket or a golf club, wherein mass particles are integrated into the equipment structure which are freely displaceable or freely movable thereto and which are provided in one or a plurality of chambers the volume of each of said chambers being small relative to the interior volume of the stroke and/or the shaft portion. The stroke characteristics of the sports equipment can be varied depending from the distribution of the chambers within the structure and/or from the amount of the mass particles used. Stroke shocks are attenuated with the result that occurrence of “tennis elbow” is diminished. Indicated is also a method for the manufacture of a tennis racket having high shock absorption and good oscillation attenuation properties and being manufactured in fiber-plastics-structure techniques. One other U.S. Pat. No. 7,192,363 issued in 2007 to Blankenship teaches a golf head with a variably dampened face. Here is shown a golf club head includes a body having a front surface, a back surface, a heel end, a toe end, a sole extending between lower portions of the heel and the toe ends, and a top rail extending between upper portions of the heel and toe ends. A face is coupled to the body through a rheological fluid. The golf club head is tuned by changing the viscosity of the rheological fluid.

U.S. Pat. No. 5,776,009 was issued in 1998 to McAtee that taught a Momentum generating golf club. Here is a momentum generating golf club comprising an elongated shaft. A resilient grip is on a top end of the elongated shaft, while a club head body is on a bottom end of the elongated shaft. The club head body has a front striking face and an internal chamber. A weight is located within the internal chamber for free movement therein. When a golfer takes a back swing the weight will move backwards in the internal chamber, to produce inertia in the direction of the back swing of the club head body to increase the extent of the back swing, thus allowing for a higher speed of the club head body in the forward swing of the golf club, so as to hit a golf ball further on the front striking face. A U.S. Pat. No. 7,037,213 issued to Otoguro in 2006 demonstrates a golf club head, in which a stable high-inertia moment is generated at the time of down swinging and impacting of a golf club, thereby reliably achieving the effect of increase in driving distance. A golf club head has a plurality of hollow chambers arranged in mutually parallel relation and in mutually adjacent relation within a head from a heel toward a toe. Each hollow chamber is faced with a sole-forming wall. A weight composed of a granular body or liquid body is sealed in each of the hollow chambers, and each of the hollow chambers is provided with an openable and closable inlet/outlet port for charging the weight into each of the hollow chambers.

None of the prior art devices provide a simple and efficient dynamic, multi-impact golf club assist device like the present driver assist. In view of the above, it will be appreciated that there exists a need for an improved dynamic, multi-impact golf club assist device which overcomes the disadvantages of the prior art devices, particularly the disadvantages noted within.

DETAILED DESCRIPTION OF PERFERRED EMBODIMENT

The present development is a dynamic, multi-impact golf club assist device. The present invention relates to golf clubs. More particularly, the present invention relates to a dynamic multi-impact golf driver having sliding pistons in the head of the driver to enhance the driving force of the driver head at the point of contact with a golf ball. The invention generally relates to a golf club head and more particularly to a golf club head having a series of movable weights incorporated therein with the movement of the weight in relation to the golf club head developing an assist in impact of the driver to the ball in predetermined locations. The instant invention relates generally to weight distributing systems and more specifically it relates to a momentum generating golf club. The momentum generating golf club produces inertia in the direction of the ball upon contact and immediately thereafter. This improvement to the driver head with the encased pitons means a golfer does not need to hit the ball precisely in the same spot every time. The pistons help to compensate and give a secondary impact to correct the ball in relation to the driver heel or toe contact point.

The advantages for the device are listed above in the introduction. Succinctly the benefits are that the device:

-   -   A. Is opposite/contiguous to the front face/ impact plate load         in weight pockets;     -   B. Is accompanied with multiple type weights in same encasement;     -   C. Uses a simple tool to adjust;     -   D. Is universal once pockets fitted;     -   E. Can have multiple gram weights; and     -   F. Means, a driver head with the encased pitons, that a golfer         does not need to hit the ball precisely in the same spot every         time.

The preferred embodiment is a dynamic, multi-impact golf club assist device 30 for a golf driver 31 comprising: (a) a plurality of chambers 40, 44, 49 from the rear of the golf driver through to the front face/ impact plate 37 of the golf driver; (b) a plurality of encased pistons 45, 42 slidably mounted in said encasement 45 of the pistons; and (c) a means 47 to removably fasten the encased pistons into the chambers of the driver head along an axis of impact of said driver head 32 with a ball 75.

The preferred embodiment is a dynamic, multi-impact golf club assist device 30 for a golf driver 31 comprising: (a) a plurality of chambers 40, 44, 49 from the rear of the golf driver through to the front face/ impact plate 37 of the golf driver; (b) a plurality of encased pistons 45, 42 slidably mounted in said encasement 45 of the pistons; and (c) a means 47 to removably fasten the encased pistons into the chambers of the driver head along an axis of impact of said driver head 32 with a ball 75. This improvement to the driver head with the encased pitons means a golfer does not need to hit the ball precisely in the same spot every time. The pistons help to compensate and give a secondary impact to correct the ball in relation to the driver heel or toe contact point.

There are today in the marketplace several drivers 31 that receive fixed weights in a weight pocket 48. To use the dynamic, multi-impact golf club assist device 30A these weight pockets 48 may be used for the preferred embodiment 30A. The piston merely replaces the fixed weight in a Taylor made, Calloway, or equivalent head. For the alternative and longer embodiment 30B, the golfer determines first that the pocket 48 extends from the back curved area 34 of the head 32 all the way to the back of the faceplate 50. If so, an externally threaded 47 encased piston 42 may be used immediately. If there is no weight pocket (i.e. not a Taylor made, Calloway, or the like equivalent) or if the weight pocket is too small in diameter or does not extend to the back of the faceplate 50, then the driver requires the chambers to be drilled and modified to accept the encased piston device 30. In this case an external thread 47 of interference fit encasement may be used with or without an adhesive. Once installed the pistons act as described below.

FIGS. 4A and 4B are sketches of the trajectory with and without the aid of the dynamic, multi-impact golf club assist device. FIG. 5 is an enlarged sketch of the trajectory with the dynamic, multi-impact golf club assist device. Demonstrated is the effect the device has on the golf ball when used with the driver. The figures explain themselves with the shown items: golf ball 75; trajectory 76 of a driven or hit golf ball 75; desired trajectory 77 (usually center of fairway); fairway edge 78; hook 81—user drives ball left; slice 82—user drives ball right; straight 83—user drives ball—middle of fairway; corrected hook 86 (boost impact at heel); corrected slice 87 (boost impact at toe); and enhanced straight 88 (boosted by added impact). As shown the diagrams, the toe area 53 of the face plate 50 may contact the golf ball 75. Accordingly, upon impact of the face plate 50 with the golf ball 75, inertia causes the piston 42 in the toe piston chamber 49 to slide forwardly on the piston guide 41 and strike the rear surface of the face plate 50. The piston 42, in combination with the forward motion of the driver head 32, propels the golf ball 75 in a generally curved ball trajectory 87 (corrected slice) such that the golf ball 75 initially leaves and then returns to the desired trajectory 77 for the golf ball 75. Consequently, the golf ball 75 lands nearer to the desired target (which, in golf play, is the golf green) then would be achieved using a conventional golf driver. Furthermore, the piston 42 enhances the forward driving motion of the driver head 32 such that the golf ball 75 achieves a greater distance than is the case with respect to a conventional golf driver 31. As shown in the middle diagram of FIG. 5, in the event that the center area 30 of the face plate 50 contacts the golf ball 75, the piston 42 in the center piston chamber 44 slides forwardly on the piston guide 41 and strikes the rear surface of the face plate 50. Consequently, the golf ball 75 is propelled in a straight and long-distance ball trajectory which approximates the desired trajectory 77. Finally, as shown in the diagram of FIG. 5, in the event that the heel area 51 of the face plate 50 contacts the golf ball 75, the piston 42 in the heel piston chamber 40 slides forwardly on the piston guide 41 and strikes the rear surface of the face plate 50. Consequently, the golf ball 75 is propelled in a generally curved ball trajectory 86 (corrected hook) such that the golf ball 75 initially leaves and then returns to the desired trajectory 77 for the golf ball 75. Therefore, the golf ball 75 lands within or closer to chipping range of the golf green than would be the case using a conventional driver.
